There may be more focus on arctic amplification and the transition of the arctic from one stable state to another with no summer sea ice, and the effects of this on Northern temperate zone weather variability. The arctic ocean and immediately adjacent land has been warming at several times the rate of the rest of the world because it is subject to a number of local positive feedback loops which have relatively little effect on total global temperatures but can mess with temperature gradients in the Northern hemisphere and thus can have a disproportionate effect on the movements of air masses. Arctic ice loss has accelerated massively in recent years and there are vague indications of a bit of a phase shift ongoing.
